4-6 Operation Method
RC03-PCR-LA
• A setting item can be changed in either the OUTPUT ON or
OUTPUT OFF condition. However, the timing of RUN (sim-
ulation start) is as described below.
When T2 = T4 = 0:
Before performing RUN, always set
OUTPUT OFF. (Then, set OUT-
PUT ON again and press the F1
(RUN) key to start a simulation.)
When T2
≠
0 or T4
≠
0: Setting items can be changed while
the OUTPUT ON condition is
maintained, and then RUN can be
performed.
9. Press the STOP key. This stops simulation of power line
abnormality.
The power line abnormality simulation can also be stopped by
pressing the ESC key. In addition, pressing the OUTPUT key
turns the output OFF as well as stopping the simulation.
10.Press the ESC key to exit the power line abnormality simu-
lation function.
If the simulation is paused using the ESC key in step 9, pressing
the ESC key again causes the simulation to be ended.
This will cancel the key-lock mode in the PCR-LA power supply.
Pressing the ESC key on the PCR-LA power supply also causes
the power line abnormality simulation to end in the same way.
• Voltage change start polarity (POL)
For the voltage change start
polarity, the zero cross regarded
as the reference for T1 is
fi
xed
to the plus zero cross. In this
case, the output voltage (wave-
form) at the L terminal, for
which the N terminal of the
PCR-LA power supply’s OUT-
PUT terminal board is used as a reference, is indicated.
To use the minus zero cross as the reference for T1, invert the
polarity of the L and N terminals on the PCR-LA power sup-
ply or add a time equivalent to a half-period of the output fre-
quency to the T1 set value.
